I've done nothing with http://www.maineyak.com, other than add the CoOp. It was created in August, and just got it's first PR, PR6.
I went from PR0 to PR3 in 3 weeks with around 1000 co-op weight allocated to this site. I havent done anything else appart from that.
I pointed 2K of weight on a newly created site for a month or two prior to this update, only other links where a few directory submissions (2 or 3). I went from pr0 to pr5.
So it's possible to increase PR with rotating links? ads from other advertsing source like Overture, Enhanced, etc?
I've never used overture or enhanced. Are they both javascript? Current guesses are that google doesn't count javascript "browser side" links...though some claim it is being spidered more and more.
All I did was add co-op to one of my sites last Thursday and I've lost 5 pounds and I can fit into my new jeans! Thanks Shawn!!!
Our site has been in the coop since January and although we have maintained number 1 rankings (with the exception of the last Google Update...BAM.. knocked us down to page 7...) we have maintained a PR5 throughout. When google determines PR, it looks to see if your link is there and then when it comes back it verifies that your link is there and then you get credit for the PR being passed... as I understand it.
A page with no natural links at all (not even from the site where it is hosted) passed from PR0 to PR4 just by using the Coop.
